    Ok, I have a 2012 DC LB 4X4 SR5, no seat heater. I looked under the little aux relay box, next to the main fuse/relay panel under the hood; there is only 1 relay... for the fog lights, but there is an empty relay socket wired, and the little lid says AIR PUMP HTR, anyone know what this is? My truck did not have a relay for this slot.
    The red/black wire (lower right in first pic) for the fog relay has 12v power only when the lights are on, the blue wire with white tracer (above the green wires in first pic) has 12v power when the the key is set to ON and also when the engine is running, regardless of headlights off/low/high.... which is how I'd like to do my "anytime fog lights mod", I would swap these two wires. I just dont know what this empty spot is, which is labled AIR PUMP HTR; Will this always have power when the truck is ON? Is this a good 12v power lead to do my mod?

    Any help here is greatly appreciated.

    Jesse

    If you do a little www.google.com, you might find the answers -
    Did a quick search....

    Here's a PDF of a corolla fuse box.
    http://www.toyota.com/t3Portal/document/om/OM12A23U/pdf/8.pdf

    Scroll down...

    40. AIR PUMP 50 A (1.8 L 4−cylinder
    [2ZZ−GE] engine): Emission control
    system
    41. HTR 40 A: Air conditioning system

    And from tacoma manuals
    http://www.ncttora.com/fsm/05+/data/ileaf/06toyrm/06toypdf/06rmsrc/rm2006ta/01200210.pdf
    http://www.ncttora.com/fsm/05+/data/ileaf/06toyrm/06toypdf/06rmsrc/rm2006ta/04600.pdf

    ANd don't forget....this fuse box could be the same fuse box/lid used for a variety of different Toyota vehicles. If you are still confused - go to your dealer and ask them.

    Thanks, but that relay spot was empty, so it cant be A/C.
    There are wires under that spot (right above the blue fog light relay), just no relay...... what is that for?

    Janster no need to be so rude about it, not everyone has the apparent time as you do to spend searching the black wholes of the internet. And your second ncttora link has diddley squat to do with that relay. He asked what it is, and if he could use it as a power source. Simply question/simple answer.

    Now to answer his question, it is a emission control device for the 2.7l that is not equipped on your truck, therefore yes you can use this as a power source for mods.

    Hey noob here yes, noob in general not. The comment is plainly put, when you see guys like the OP and myself it should be understood that we maybe have lives going on and dont have the hours to put in front of a computer to generate 10k and 30k plus posts.

    However it is noted, and I will structure my comments in the future as to not be considered offensive. But as you told me to calm down, take a second to think maybe my comment was meant just the same as yours to me.

    Food for thought.

    Please re read what I said sir.. I will restructure as not to offend yourself or other, now I think OP's thread has been jacked enough, end of conversation.
